I made a white cake and followed the instructions on the box. Divided the batter into 6 bowls and added food coloring. Layered it and baked it as directed. Can be made into cupcakes, a bunt pan, or two 8 inch rounds. So easy and so pretty as a final product. Made for my daughter's 7th birthday cake- she loved it!
rainbow cake - would be fun for the boy but who am i kidding - it would be for me too :)
